The girl explains to Yuji that she is a Flame Haze, someone who supervises and restores balance between the Crimson world and the one Yuji lives in, and that torches will eventually go out. She tells him that he is also a Mystes, someone who possesses a Treasure Tool (Hōgu) in his body, although she is unsure what the treasure is. Yuji fails to understand immediately, and she shows him a classmate of his–Yukari Hirai–who is also a Torch and is about to burn out. Despite trying to save her, Hirai eventually burns out from existence. Yuji decides that the Flame Haze (who's known as the Flame-Haired, Blazing Eyed Hunter, in possession of the sword Nietono No Shana) needs a name and calls her Shana, after her sword.
